react-router v6嵌套路由简单案例

​

 react-router V6版本路由用法和V5用法差距较大,一个简单的使用案例

新版本组件也开始使用函数式组件+hooks

"react-router-dom": "^6.2.1",

1.入口main 

import "./App.css";
import { BrowserRouter, Route, Routes, Navigate } from "react-router-dom";
import Index from "./modules/index/Index";
import Error from "./modules/error/Index";
import Admin from "./modules/admin/Index";

const App = () => {
    return (
        <div className="App">
            {/* HashRouter哈希路由 还是 Browser路由随需求选择 */}
            <BrowserRouter>
                <Routes>
                    {/* 默认初始化入口/home*/}
                    <Route path="/" element={<Navigate to="/home" />} />
                    {/* home模块路由 */}
                    <Route path="home/*" element={<Index />} />
                    {/* admin模块路由 */}
                    <Route path="/admin/*" element={<Admin />} />
                    {/* 404页面 */}
                    <Route path="*" element={<Error />} />
                </Routes>
            </BrowserRouter>
        </div>
    );
};

export default App;

 

2.子路由-Index模块(案例举例)

import { Route, Routes } from "react-router-dom";
import MainIndex from "./page/index/Index";
import Nav from "./page/nav/Nav";

import Error from "../error/Index";


const Index = () => {
    return (
        <div>
            <Routes>
                    {/* path="/"初始化默认 */}
                    <Route path="/" element={<MainIndex />} />
                    <Route path="/nav" element={<Nav />} />
                    {/* 子路由的404页面 */}
                    <Route path="*" element={<Error />} />
                </Routes>
        </div>
    );
};
export default Index;

 

3.路由跳转方法2种 useNavigate, Link

import { useNavigate, Link } from "react-router-dom";

const Child = (props) => {
    const navigate = useNavigate();
    return (
        <div>
            {/* link跳转 */}
            <Link to="/admin/componentDelivery">跳转路由</Link>
            <br />
            <div onClick={() => {
                // 逻辑跳转
                navigate("/admin/componentDelivery");
                // replace 跳转
                // navigate('/home', {replace: true});
                // navigate("/");
            }}></div>
           
        </div>
    );
};
export default Child;
